To increase its revenue contribution to 20-25%, from single digits, in addition to synergising passenger routes with airlines in its group to improve efficiency as airfares rise, AirAsia X plans to ramp up its cargo service. Air Asia X is the long-haul affiliate of AirAsia and Unilode Aviation Solutions. Tony Fernandes, acting group chief executive of AirAsia X, said cargo services will make up a bigger proportion of total revenue over the next few years. In addition to its current wide-body Airbus A330 fleet, AirAsia X might also use the narrow-body Airbus A321 for cargo flights. The company is planning to add 362 A321 jets from the second quarter of next year until 2035, and the plane could be more efficient for shorter routes than the A330.
